Sorry, I am not following. What do you mean by "host-specific
information"? If system has no way to detect how many factors were involved
in authentication, how would I be able to guarantee that only 2FA is
allowed via this box?
I suppose this can work: I can write code that will:
1 - detects if there are OTP numbers at the end of the password
2 - authenticates using full 2FA
3 - authenticates using just password without 2FA
And then authenticate only if all 3 conditions are satisfied. Seems a bit
hacky, but that is the only way I can think that may work.
Alternative is to set up 2 users for each actual user, one for border and
one for internal auth. Force 2fa on border user. Only allow border users
on border boxes.
Am I missing anything?
